Abstract:
I will discuss how low energy neutrino data, from neutrino mixing and
absolute neutrino mass scale experiments, could provide in the next
years hints on the solution of one of the big mysteries of our Universe,
why it is matter dominated. The mechanism responsible for the
generation of a matter-antimatter asymmetry might be related to
properties of neutrinos and in particular to the mechanism that
generated the tiny neutrino masses tested in neutrino mixing
experiments, so called Leptogenesis. After an initial review of general
scenarios of properties I will focus on a particular solution that, in
light of the most recent experimental results, would be able not only to
explain the generation of the asymmetry but also its sign, namely why
matter was favoured over anti-matter, relating it to CP violation in
neutrino mixing.
